Description

Deckenleuchte mit einem länglichen Leuchtengehäuse Ceiling lamp with an elongated lamp housing
Die Erfindung bezieht sich auf eine Deckenleuchte mit einem länglichen Leuchtengehäuse, bestehend aus einem wannenformigen Oberteil, das mit Fassungen zur Aufnahme von mindestens einer Leuchtstoffröhre, mit Halterungen für die zugehörigen elektrischen Vorschaltgerate und Kabel sowie mit Befestigungselementen zur Verankerung des Oberteils in der Decke versehen ist, und einem an einer Längskante des Oberteils schwenkbar gelagerten, Licht - durchlässigen Unterteil mit lösbaren Rastelementen zur Verbindung mit dem Oberteil.The invention relates to a ceiling lamp with an elongated lamp housing, consisting of a trough-shaped upper part, which is provided with sockets for receiving at least one fluorescent tube, with holders for the associated electrical ballasts and cables and with fastening elements for anchoring the upper part in the ceiling, and a light-permeable lower part pivotably mounted on a longitudinal edge of the upper part with releasable locking elements for connection to the upper part.
Deckenleuchten dieser Art sind allgemein bekannt und werden insbesondere zur Ausleuchtung von Büroräumen, Werkräumen, Lagerhallen und sonstiger Arbeitsräume verwendet. Bei diesen Deckenleuchten kommt es darauf an, daß sie leicht zu handhaben und einfach zu montieren sind. Wichtig ist aber auch, daß das Unterteil zum Auswechseln von Leuchtstoffröhren leicht zu öffnen und wieder zu verschließen ist. Da die Deckenleuchten je nach Raumgröße in großen Stückzahlen benötigt werden, ist wegen der Anschaffungskosten außerdem anzustreben, daß diese Leuchten möglichst billig in der Herstellung sind.Ceiling lights of this type are generally known and are used in particular for illuminating offices, workrooms, warehouses and other workrooms. It is important with these ceiling lights that they are easy to handle and easy to assemble. However, it is also important that the lower part for replacing fluorescent tubes is easy to open and close again. Since the ceiling lights are required in large numbers depending on the size of the room, it should also be aimed at because of the purchase costs that these lights are as cheap to manufacture as possible.
Aus der EP 0 726 420 B1 ist eine Deckenleuchte der eingangs genannten Art bekannt, welche aus einem geschlossenen zweiteiligen Gehäuse besteht. Beide Gehäuseteile sind aus Kunststoff hergestellt, wobei das Unterteil, die sogenannte Abdeckung mittels Befestigungselementen lösbar am Oberteil, dem sogenannten Gehäusebasisteil befestigt wird.From EP 0 726 420 B1 a ceiling lamp of the type mentioned is known, which consists of a closed two-part housing. Both housing parts are made of plastic, with the lower part, the so-called cover, being releasably attached to the upper part, the so-called housing base part, by means of fastening elements.
Als Befestigungselemente sind vier sogenannte Schnellverschlüsse vorgesehen, die an den Breitseiten des Gehäuses in dessen Endbereich einander gegenüberliegend angeordnet sind. Die Schnellverschlüsse sind vorzugsweise durch C-förmige Spangen gebildet, die mit einem zapfenförmigen Spangenbasisteil in der unteren Rinne klemmend gehalten sind, und deren obere krallenförmigen Verschlußenden den Boden der oberen Rinne mit Klemmwirkung übergreifen. Verschlußelemente ist der Zusammenbau der Deckenleuchte sehr kompliziert und arbeitsintensiv. Auch beim Auswechseln von defekten Leuchtstoffröhren ist der Monteur stark gefordert und wird diese Arbeit wohl kaum ohne fremde Hilfe bewerkstelligen können. Besonders nachteilig erscheint hierbei die Tatsache, daß er die Abdeckung nach dem Lösen der Verschlußteile Zwischenlagern muß, damit er beide Hände für den Auswechselvorgang frei hat. Keine Frage, daß diese Deckenleuchte nicht nur teuer in der Herstellung und im Zusammenbau ist, sondern zum Auswechseln der Leuchtstoffröhren auch stets einen Handlanger erfordert.Four so-called quick-release fasteners are provided as fastening elements, which are arranged opposite one another on the broad sides of the housing in its end region. The quick-release fasteners are preferably formed by C-shaped clasps, which are held in the lower channel by a pin-shaped clasp base part and whose upper claw-shaped closing ends overlap the bottom of the upper channel with a clamping effect. Closure elements, the assembly of the ceiling light is very complicated and labor intensive. The fitter is also challenged when replacing defective fluorescent tubes and will hardly be able to do this work without outside help. Particularly disadvantageous here is the fact that he has to temporarily store the cover after loosening the closure parts so that he has both hands free for the replacement process. There is no question that this ceiling light is not only expensive to manufacture and assemble, but also always requires a henchman to replace the fluorescent tubes.
Aufgabe der Erfindung ist es, eine Deckenleuchte der vorgenannten Art zu schaffen, bei der diese Nachteile beseitigt sind. Diese Aufgabe wird bei der eingangs beschriebenen Deckenleuchte nach der vorliegenden Erfindung dadurch gelöst, daß das Oberteil und das Unterteil einstückig aus Kunststoff verspritzt wird und daß ferner das Unterteil und das Oberteil an jeweils einer Längskante mittels eines sogenannten Filmscharniers schwenkbar miteinander verbunden sind.The object of the invention is to provide a ceiling lamp of the aforementioned type, in which these disadvantages are eliminated. This object is achieved in the ceiling lamp according to the present invention described in the introduction in that the upper part and the lower part are injection-molded in one piece from plastic and in that the lower part and the upper part are each pivotally connected to one another by means of a so-called film hinge.
Hierdurch lassen sich nicht nur die Herstellungskosten beträchtlich senken, sondern auch die Handhabung beim Zusammenbau des Leuchtengehäuses und vor allem das Öffnen und wieder Verschließen des Unterteils beim Wechsel der Leuchtstoffröhren vereinfachen. Durch das einstückige Abspritzen des Leuchtengehäuses läßt sich das Unterteil in weiterer Ausbildung der Erfindung auf einfache Weise so gestalten, daß es aus einem Rahmen mit über die gesamte Länge quer verlaufenden, im Profilquerschnitt V-förmig ausgebildeten Verbindungsrippen besteht.This not only significantly reduces the manufacturing costs, but also simplifies handling when assembling the luminaire housing and, above all, opening and closing the lower part when changing the fluorescent tubes. Due to the one-piece spraying of the lamp housing, the lower part can be designed in a simple manner in a further embodiment of the invention in such a way that it consists of a frame with connecting ribs running across the entire length and having a V-shaped profile cross section.
Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen und der nachfolgenden Beschreibung eines in der Zeichnung dargestellten bevorzugten Ausführungsbeispiels der Erfindung. Es zeigen:Further features of the invention emerge from the subclaims and the following description of a preferred exemplary embodiment of the invention illustrated in the drawing. Show it:

Die in den Figuren dargestellte Deckenleuchte besteht im wesentlichen aus einem länglichen, wannenformigen Oberteil 1 und einem Licht - durchlässigen Unterteil 2. Beide Teile sind einstückig aus Kunststoff verspritzt und an einer Längskante mittels eines sogenannten Filmscharniers 3 schwenkbar miteinander verbunden.The ceiling lamp shown in the figures consists essentially of an elongated, trough-shaped upper part 1 and a light-permeable lower part 2. Both parts are injection-molded in one piece from plastic and pivotally connected to one another at one longitudinal edge by means of a so-called film hinge 3.
Das Oberteil 1 ist an den Innenseiten beider Stirnwände 4 mit Fassungen 5 zur Aufnahme von mindestens einer Leuchtstoffröhre 6 versehen. In der Decke 7 des O- berteils 1 sind außerdem Halterungen 8 und Klemmen 9 für die zugehörigen Vorschaltgerate und Kabelleitungen integriert, welche zum Betreiben von Leuchtstoffröhren 6 üblicherweise benötigt werden.The upper part 1 is provided on the inside of both end walls 4 with sockets 5 for receiving at least one fluorescent tube 6. Brackets 8 and terminals 9 for the associated ballasts and cable lines, which are usually required for operating fluorescent tubes 6, are also integrated in the ceiling 7 of the upper part 1.
Das Unterteil 2 besteht aus einem Rahmen 10 mit über die gesamte Länge quer verlaufenden, im Profilquerschnitt V - förmig ausgebildeten Verbindungsrippen 11. Zur lösbaren Befestigung des Unterteils 2 am Oberteil 1 sind am Rahmen 10 auf der dem Filmscharnier 3 gegenüberliegenden Seite Rastelemente 12 angeformt, die beim Einschwenken des Unterteils 2 in das Oberteil 1 in Richtung des Pfeiles „E" in entsprechend große Aussparungen 14 in der Längswand 13 einrasten (Fig.3 und 5).The lower part 2 comprises a frame 10 with connecting ribs 11 running transversely over the entire length and having a V-shaped profile cross section. For releasable attachment of the lower part 2 to the upper part 1, latching elements 12 are formed on the frame 10 on the side opposite the film hinge 3 when pivoting the lower part 2 into the upper part 1 in the direction of arrow “E”, engage in correspondingly large cutouts 14 in the longitudinal wall 13 (FIGS. 3 and 5).
In den Längswänden 13 des Oberteils 1 sind auf beiden Seiten über die Außenfläche vorstehende Rasthaken 15 vorgesehen, welche , wie aus Fig. 4 ersichtlich, über Federstege 18 an den Längswänden 13 elastisch zusammendrückbar angeformt sind. Diese Rasthaken 15 sind so dimensioniert, daß sie beim Einführen des Leuchtengehäuses in eine dem Oberteil 1 angepaßte Aussparung 16 in der Deckenplatte 17 in Richtung des Pfeiles „M" (Fig.2) bis hinter die Außenfläche ausweichen und an- 19 der Aussparung 16 einrasten.In the longitudinal walls 13 of the upper part 1, latching hooks 15 projecting beyond the outer surface are provided on both sides, which, as can be seen in FIG. 4, are integrally molded on the longitudinal walls 13 via spring bars 18 in an elastically compressible manner. These latching hooks 15 are dimensioned such that when the luminaire housing is inserted into a recess 16 in the ceiling panel 17 which is adapted to the upper part 1, in the direction of the arrow “M” (FIG. 2), they dodge behind the outer surface and 19 engage the recess 16.
In den beiden Stirnwänden 4 des Oberteils 1 sind an den Außenseiten jeweils ein Anschlußstecker 20 und eine Anschlußbuchse 21 integriert. Dadurch ist es möglich, mehrere Leuchtengehäuse mit entsprechend integrierten Steckern 20 und Buchsen 21 elektrisch miteinander zu verbinden und dadurch die Gesamtlänge der Deckenleuchte beliebig zu verlängern.In the two end walls 4 of the upper part 1, a connector 20 and a connector socket 21 are integrated on the outer sides. This makes it possible to electrically connect a plurality of luminaire housings with correspondingly integrated plugs 20 and sockets 21 and thereby extend the overall length of the ceiling luminaire as desired.
Die Decke 7 des Oberteils 1 kann an seiner Unterseite vorteilhafterweise durch entsprechende Wölbungen als Reflektor 22 ausgebildet sein, auf welchen zu diesem Zweck eine gut reflektierende Metallschicht aufgetragen wird, so daß die Lichtstrahlen der Leuchtstoffröhre - wie bei einem Metallgehäuse - voll nach unten geleitet werden. The ceiling 7 of the upper part 1 can advantageously be formed on its underside by corresponding curvatures as a reflector 22, on which a well reflecting metal layer is applied for this purpose, so that the light rays of the fluorescent tube - as in a metal housing - are guided fully downwards.
